IMPROVEMENT IN APPARATUS FOR GENERATING AND CARBURETING HYDROGEN-GAS.

Specification forming part of Letters Patent No. 118,983, dated September 12, 1871.

To all whom it may concern:

Be it known that JOHN B. TERRY, late of Brooklyn, in the county of Kings and State of New York, deceased, did, during his lifetime, invent certain new and useful Improvements in Apparatus for the Manufacture of Gas, of which the following is a specification:

The invention relates to apparatus in which hydrogen or other gas is first generated and then passed through a carbureter for the purpose of enriching it and making it more illuminant. The nature of the invention will be best understood by reference to the accompanying drawing, representing a hydrogen-gas generator and carbureter.

Figure 1 is a vertical central section of the apparatus complete. Fig. 2 is a like sectional View of the dome in which the hydrogen-gas is generated. Fig. 3 is a like sectional View of the purifying portion of the apparatus, the line of section being at right angles with that in Fig. 1. The remaining figures are views of detached parts, which will be hereinafter referred to.

The hydrogen-gas generator is composed of the dome A, open at the bottom and provided at a suitable distance above the same with a punctured or perforated screen, a, shown in plan in Fig. 4, for receiving the metal to be acted on by the acid solution. The dome sets within a cylindrical case, B, arovided with a bottom, on which the legs I) of the dome rest, these legs being employed in order to allow the acid solution in the case to have free access to the dome, and vice versa. The top or contracted portion A of the dome is secured to the center of the cover of the cylindrical case B, so that the cover assures the dome in proper position, and, when lifted off from or placed on the case, will carry the dome with it. There is an opening, 0, in the top of the cover, through which the acid can be poured in, and a stop-cock, cl, at the bottom of the case, for drawing the same of when necessary.

The operation of this portion of the apparatus will be readily understood. The contact of the acid solution and metal in the dome generates a gas, which passes off through the pipe f. \Vhen no more gas is required the pipe is closed and the pressure of the gas, which still continues to be generated so long as the solution is in contact with the metal, will soon force the solution down away from the metal, and up under the bottom of the dome, into the annular space between the dome and case. As soon as this takes place the generation of gas of course ceases. The gas, as it issues from the generator, is conducted through the pipe finto one compartment, 9, of a purifier, O, seen in horizontal section in Fig. 6, filled with excelsior or other suitable material. Passing through this purifier, it is conducted through a pipe, It, into a carbureter, D, of any suitable construction, where it is carbureted in the usual manner, and thence returns through the pipei into the purifier O, passing through the other compartment j of the same, filled, like the first, with some purifying compound or material, and thence itissues through the pipe 70 to the burner.

The carbureter and purifier may be arranged in any suitable manner with respect to the gasgenerator, but it is preferred to arrange them as shown in the drawing. The purifier is placed on the side of the generator or case B, as shown, connecting with the generator and the carbureter, as represented and already described.

The carbureter D is placed beneath the generator, surrounded by the case B or a prolongation of said case, so that between the sides of the two there may be an annular chamber, to be filled with water or some non-con ducting material, in order to give a more equable temperature to the carbureting liquid, which is supplied to the carbureter through the pipe I. The gas conducted through pipe it into the carbureter passes through a vertical sect-i011 of the pipe arranged centrally within the carbureter, and carrying on its lower end a loose hub, m, with radial arms '22, both hub and arms being tubular or hollow to receive the gas issuing from the lower end of pipe it into the hub. The level of the liquid in the carbureter is considerably above the top of the hub and arms, so that the latter are immersed therein. The arms are closed at their outer ends, communicate at their inner ends with the hub, and are each provided with a series of small holes or perforations, through which the gas discharges into the carbureting liquid, the rows of perforations in all the tubes being arranged on the same side, so that the action of the gas discharged upon the liquid will cause the hub and arms to revolve, thus keeping the liquid in motion and maintaining it in better condition to carburet the gas.

An apparatus thus arranged and put together is exceedingly compact and occupies but little room. The generation of gas can be instantly checked whenever desired, while, by the combined action of the generator, purifier, and carbureter, a gas of great brilliancy and excellent quality is produced at a verylow cost. The apparatus, too, is simple of construction, can be made cheaply, requiresbut little attention, and is not liable to get out of order.

What is claimed as the invention of the said JOHN B. TERRY is as follows:

1. The combination of the hydrogen-gas generator, the carbureter, and the purifier, through which the gas, both before and after carburation, passes, substantially as shown and described.
